Therefore, the dimensional ratios (φ of spring tube 2/ φ 1) preferably be set in 0.56 to 0.72 the scope.Dimensional ratios (φ 2/ φ 1) be set in 0.60 to 0.68 the scope then better.The thickness η of spring tube preferably is set in 23 to 35mm the scope, and better in 28.7 to 30.0mm scope.
If the thickness η of spring tube 24 surpasses 35mm, the bonding surface of reinforced layer 41,42,43,44 just is easy to break away from from body.If its thickness η is less than 23mm, the power that is used to make the spring tube 24 that is crushed to return to original shape so will reduce.In addition, in this case, heat will make gluing of surfaces break away from from body 40.
As shown in Figure 3, by the rubber layer that reinforced layer limited of innermost layer, or the thickness γ of first reinforced layer 41 and spring tube 24 internal surfaces 243 is set in 10 to 15mm the scope.As shown in Figure 4, when foreign matter 48 was contained in the spring tube 24, rubber layer prevented first reinforced layer 41 of foreign matter 48 cutting spring tubes 24.
Shown in Fig. 6 and 9, the spring tube 24 of present embodiment is with the internal surface setting of semicircular form along cylinder 11.The radius of curvature R of spring tube 24, promptly the distance of the axle O2 from the center O 1 of cylinder 11 to spring tube 24 is determined as follows.
When spring tube 24 straight-line extensions, the cross section with an annular.When its part was contained in the cylinder 11, as shown in Figure 9, spring tube 24 produced deformation.So as shown in figure 10, this spring tube 24 has a plurality of stepped serrations.In this state, the major axis D1 of internal surface 241 be set at the concentric plane of the internal surface of cylinder 11 on, as shown in figure 10, its minor axis D2 extends perpendicular to the internal surface of cylinder 11.The ratio of minor axis D2 and major axis D1, or ((D 2/ D 1) * 100) indicate the compressibility τ of spring tube.When compressibility τ diminished, the intake of pump also diminished.
When spring tube 24 was bent, as shown in Figure 9, a tension force acted on spring tube 24 and the external lateral portion that cylinder 11 contacts, and the masterpiece of a compression is used to break away from the inside part of cylinder 11.So radius of curvature R diminishes, to reduce the compressibility τ of spring tube.If spring tube 24 is exceeded its yield point (promptly recovering the limit) bending, the power on the spring tube 24 of acting on so is just greater than the resistance to flexure T of spring tube.This just makes the inside part bending of spring tube 24, shown in the dotted line of Fig. 9.
In this embodiment, the compressibility τ of spring tube is determined by following equation: corresponding to reducing of the compressibility of spring tube 24, and the reducing and will remain on below 10% of suction, thus prevented the bending of pipe:
τ＝〔(D2/D1)×100〕≥90％??…(1)
The radius of curvature R of spring tube, thickness η, rigidity G and internal diameter φ 2With external diameter φ 1Ratio (φ 2/ φ 1) should satisfy the requirement of equation (1).The rigidity G of spring tube depends on number N and angle of revolution α (41 to 44 relative O of layer thereof of first to fourth reinforced layer 41-44 2The inclination angle, as shown in Figure 9), the thickness of spring tube 24 and the hardness Hs of rubber.
For determining radius of curvature R and internal diameter φ according to the spring tube 24 of equation (1) 2Between relation, we have done an experiment.The result is shown in the curve of Figure 11.Shown in this curve, radius of curvature R and internal diameter φ 2Ratio, or R/ φ 2Be about 4.0.And for guaranteeing safety, R/ φ 2It is best approximating 5.0.
When spring tube 24 is bent, an external force W (kg) along perpendicular to the pipe 24 axis directive effect in the pipe 24 on.Like this, the circular cross section of pipe 24 just is deformed into an ellipse.In this state, spring tube 24 produces the power of this external force of opposing, or resistance to bending T (kg).As external force W during greater than resistance to bending T, radius of curvature R is corresponding to the bending resistance bending radius, and resistance to bending T is corresponding to a limit resistance to bending.
Resistance to bending T is determined by following equation (2), and the rigidity G of spring tube 24 is determined by following equation (3):
T＝k1×(η nφ2 m)×G r…(2)
G＝k2×N×E?????????????…(3)，
K1 wherein, k2 is a constant, index n, m, the numerical value of r for drawing by experiment, N is the number of reinforced layer 41 to 44, E is a constant, this constant is based on the material of reinforced layer 41 to 44, and the fiber thickness of reinforced layer and final number (fibre number that is comprised in the per inch (25.4cm)) thereof are determined by experiment.
In addition, the flexural property of the angle of revolution α of reinforced layer 41 to 44 influence pipe 24.If angle of revolution α is zero, pipe just is difficult to bending so, and is easy to bending resistance.But pipe is not easy to the axial tension by acting on the interior pressure of pipe.Therefore, angle of revolution α generally is set in the scope of 50 to 70 degree, is preferably in the scope of 50 to 60 degree.In the present embodiment, angle of revolution α is set to 54 ' 55 ".This structure can be between axial component that acts on the power on the pipe and radial component equilibrium establishment.
Generate internal diameter φ 2Be respectively 38,50,75 and several spring tubes 24 of 100mm, with the compressibility τ that determines each pipe 24 and the relation of radius of curvature R.The result as shown in figure 12.Can obtain the radius of curvature R of spring tube according to curve shown in Figure 12, radius of curvature R is determined by equation (4):
R＝K 3×(φ 2+η)×(φ 2/η)??…(4)，
K wherein 3∝ (1/G) ... (5).
If the value of N, or the number of reinforced layer 41 to 44 increases in equation (3), and the rigidity G that occurs in equation (3), (5) also will increase so.This just makes the constant K that appears in equation (4), (5) 3Value reduce.If constant K 3Reduce, remain unchanged even manage 24 thickness η and compressibility τ thereof, the radius of curvature R of being determined by equation (4) also will diminish so.The rubber hardness Hs relevant with rigidity G generally is set in the scope of 50 to 70 degree.In addition, constant K 3According to the vary in diameter of cylinder 11, and be set in 0.8 to 1.2 the scope.
Design also produces nominal diameter and is respectively 38,50, and 75 and several spring tubes of 100mm, thus obtain by equation (1) and the compressibility τ that determines according to experiment equation (4).Table 2 shows the calculated value and the actual value of spring tube 24 radius of curvature R, and the actual value of the compressibility τ of spring tube 24.The internal surface of cylinder 11 has a radius, and this radius is by spring tube external diameter φ 1Half add the actual value of radius of curvature R and draw.
